CDK8-Dependent Expression of ERF and Plant Defensin Genes.

(A) Induced expression of genes encoding the TFs ERF1, ORA59, and ERF2 is reduced in the cdk8 mutant.

(B) Induced expression of defensin genes is dependent on CDK8.

Total RNAs were extracted from 5-week-old plants grown in soil before and after B. cinerea inoculation. Relative transcript levels were normalized with Arabidopsis ACT2. The normalized expression level of the wild type at 0 h was set to 1. Error bars indicate se (n = 3). Three independent biological replicates were performed. Significance of differences between the mean values was analyzed statistically (Student’s t test, *P < 0.05, **P < 0.01).
